A PDP-11/40 setup.

The PDP-11/40, introduced in 1973, was the first machine to introduce 18-bit memory addressing on the PDP-11 platform.

The OEM version of the 11/40 is the 11/35. A special 11/40 with a blue front panel was used as the front-end for the KL-10 in DECSystem-10s and DECSystem-20s---though the 11/40 panel was hidden behind a cabinet door on the 20.

The 11/40 was also the primary platform for early UNIX.
